Abstract In this study, in respect of “The Black Sea Pollution Monitoring Project”, the distribution of the qualitatively phytoplankton in the samplings during the periods of September 2004, April 2005 and October 2005 along the Turkish coasts of the Black Sea has been investigated and also has been presented a species list. The acquired list of the species will contribute so much to the phytoplankton control list of Turkish Coasts of the Black Sea. A total of 129 taxa belonging to 7 classes were identified in qualitative and quantitative samples. Diatoms represented the majority of the community (52.7 %), followed by dinoflagellates (36.4 %). Especially in the water samples of river inputs belonging to 4 classes were determined totally 12 fresh water algae species.
